Embodiment 1

[0015] The total weight of each component in this embodiment is 10kg, and the weight percentage of each component is:

[0016] Tebuthiazone technical 20%,

[0017] Wetting agent: isotridecyl alcohol polyoxyethylene ether 0.5%,

[0018] Dispersant: 2% triphenylethyl phenol polyoxyethylene ether phosphate triethanolamine salt, 2% sodium styrene acrylate,

[0019] Thickener: 0.2% sodium carboxymethyl cellulose,

[0020] Defoamer: dimethyl silicone oil 0.2%,

[0021] Antifreeze: propylene glycol 4%,

[0022] Preservative: POM 0.1%,

[0023] Water 71%.

[0024] The preparation method is:

[0025] ① First mix sodium carboxymethyl cellulose and polyformaldehyde with half of the water to form a liquid mixture of sodium carboxymethyl cellulose and polyformaldehyde.

[0026] ②After mixing the remaining raw materials with the other half of the water, use a sand mill for multiple cycles of wet pulverization until the particles in the mixture have a fineness of 1 μm to 5 μm, thereby obtaining a suspension...

Abstract

The invention discloses a suspending agent of tebuthiuron. The suspending agent of tebuthiuron comprises the following components in percentage by weight: 20 to 50 percent of raw medicament of tebuthiuron, 0.5 to 5 percent of wetting agent, 1 to 10 percent of dispersing agent, 0.1 to 5 percent of thickening agent, 0.1 to 2 percent of defoaming agent, 1 to 10 percent of preservative, and the balance of water, wherein the dispersing agent is one or two of triphenyl ethylphenol polyethenoxy ether phosphate ester triethoxide, alkylphenol polyethenoxy ether sodium sulfonate, triphenylethylene phenol polyethenoxy ether, triphenylethylene phenol polyoxyethylene polyoxy propylene ether; and the wetting agent is fatty alcohol polyethenoxy ether and / or alkylphenol polyoxyethylene succinate sulfonate. The suspending agent is good in dispersibility and fluidity and high in suspension rate and can be directly sprayed or mixed with water in any ratio and then sprayed, so that the suspending agent is conveniently used and does not pollute the environment.

Description

Technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to a tebufenuron suspension and a preparation method thereof. Background technique [0002] Pesticide suspension is a pesticide formulation prepared from water-insoluble solid technical, pesticide additives and water through wet superfine pulverization. Its advantage is that it can be uniformly mixed and dispersed with water in any proportion, is not affected by water quality and water temperature, is convenient to use, is not easy to pollute the environment, and can be sprayed directly or sprayed after dilution. It is currently recognized as an environmentally friendly formulation. [0003] Tebuthiazol (ie N-(5-terbutyl-1,3,4,-thiadiazol-2-yl)-N,N'-dimethylurea) is a kind of biocidal urea Herbicides have good control effects on annual and perennial grasses and broad-leaved weeds, and can be used to prevent non-arable land weeds, shrubs in pastures, grasses and b...
